Simplescalar crosscompiler problem |
|
|
Hi all,
when i compiled SPEC CINT2000 186.Crafty this banchmark using
simplescalar crosscompiler, it generated the following error message
:
/tmp/cc0W3t6C.s: Assembler messages:
/tmp/cc0W3t6C.s:53: Error: unrecognized opcode `fixme'
/tmp/cc0W3t6C.s:58: Error: unrecognized opcode `b 3f'
/tmp/cc0W3t6C.s:82: Error: unrecognized opcode `fixme'
/tmp/cc0W3t6C.s:87: Error: unrecognized opcode `b 3f'
Does anyone know how to solve this problem ??
After i grep gcc source code i think it maybe cause by insn-output.c

static char *
output_110 (operands, insn)
rtx *operands;
rtx insn;
{
{
operands[4] = const0_rtx;
dslots_jump_total += 3;
dslots_jump_filled += 2;
return "FIXME\n
sll\t%3,%2,26\n\
\tbgez\t%3,1f\n\
